A Leaky Air Conditioner? Here’s What May Be Happening

Monday, May 20th, 2019

water-dropletsWhen your home’s air conditioning system is running during the summer, you will occasionally hear the sound of water dripping coming from the indoor cabinet. This is normal—you are hearing the sound of the water condensation that collects along the evaporator coil dripping down into a pan beneath it. This water (called condensate) is a standard part of how your central air conditioning system removes heat from the air. Once the water collects in the condensate pan, it leaves the house through a drain and line that leads to the outside.

However, you only want to hear water dripping in the air conditioner. You don’t want to actually see water leaking from the unit and pooling around it. When this happens, it means a problem in the condensate removal system that needs to be fixed.

Below, we’ll look at why you may have water leaking from your AC system.

Residential central air conditioning has a long history going back to the 1920s. But many decades would pass before central AC systems became common and affordable for homeowners.

The central air conditioning system has replaced the old window units that were once the main way for homes to enjoy cooling. Window units have a limited use, conditioning only small areas. They’re also unattractive-looking, block light, and make a home less secure. All around, central air conditioning is the superior choice for a home, and it also allows for indoor air quality improvement additions.

When the Second Floor Keeps Getting Too Hot!

Thursday, April 11th, 2019

thermometer-going-redTwo-story homes often encounter problems with their upper floors getting much warmer than the lower floors. Heat rises, so heat tends to gather in the upper levels of a house. Another cause is heat coming through the roof on sunny days. A hot upper floor can happen even in a home with a powerful heating and air conditioning system and well-designed ductwork, and it can occur at any time of the year. However, ineffectual ducts and malfunctioning comfort systems can contribute to the problem.
